AXLE AND AXLE-BOX.

SPECIFICATION forming part of Letters Patent No. 590,995. dated October 5, 1897.

Application filed February 1891' Serial 110.323.1393. F0 model) To all Ir/mm i/ may (.(II/(flll'lb;

lie it known thatl, MIRON D. MACK, of Kneeland. in the county of Racine and State of \Visconsin,have invented a new and useful 5 improvement in Vehicle-Axles and Axlelioxes, of which the following isa description, reference being had to the -2t('(t0lt'l[)2lt1 \'lng d awings, which are a part of this specification.

My in vention has relation to improvements in vehicle-axles and axle-boxes.

The object of the device is to effectually provide on the one hand fol-excluding all dirtor sediment; and on the other to prevent the escape of the oil or lubricant.

\Vith the above primary objectin view the invention consists of the devices and partsor their equivalents; as hereinafter more fully set forth.

In the accompanying drawings, Figurel is a detail of one end of an axle of my improved construction, showing the packing, before being compressed,in proper position thereon.

Fig. 2 is a similar view of the axle, showing the box thereon and the packings com pressed into. the annular grooves, said box being in longitudinal section. Fig. 3 isa cross-section on the linfi- 3 of Fig. 2. Fig. 4 is a detail view of op of the packing-rings; and Fig. 5 is avl'w of a modified form of one end of the axle and axle-box with the nut on the end thereof, said box and nut beinginsection. Referring to the drawings, the numeral 6 indicates the main portion of the axle, terminating atits extremityin thespindle 7. At the point where the spindle joins the main portion of the axle an annular shoulder 8 is formed, and immediately in advance of said shoulder the spindle is provided with anonnular groove 9. At a short distance outwardly from the annular groove the spindle is ad visably formed with another annular shoulder 10, the spindle from this latter shoulderoutwardly being of a reduced diametor, leaving the portion 1L between the shoulders 8 and 100i? a somewhat greater diameter than the remaining portion of the spindie,but 'of less diameter than the main portion of the axle. Near its outer end the spindle is provided with a third shoulder 12, and immediately in advance of this shoulder with an an- 'nuiar groove 13. From this annular groove. the spindle continues outwardly in a reduced. extremity, the inner portion thereof being plain. as indicated at 14, and the remaining portion threaded.

'lhe numeral 15 indicates the axle-box. This box is adapted to receive therein the axle-spindle and to closely embrace the spindle, including the portion 11 thereof. This box is provided with an interior'annularshoulder 16, which is opposed to the shoulder 80f the axle and is also formed with an annular groove 17, which registers with theannular groove 9. The extremity of the bore of this box is somewhat-enlarged to fit closely around the axle proper. In cases where the spindle is provided with the shoulder 10 the box is correspondingly shouldered. as indicated at 18. and between these two shoulders is advisably interposed a packing 19. The remaining [)(fi'l ion of the bore of the box is of a reduced diameter to fit the correspondingly-re duced portion of the spindle. Near its outer end the box is provided interiorly with a shoulder 20 and just in front of this shoulder with an annular groove 21; registering with the annular groove 13 of the spindle. The extreme outer end of the bore ofthe box is reduced in diameter to fit snugly around'the 8o plain or unthreadedportion 14 of the reduced extremity of the spindle. The box is held in position on the axle by means or a nnt 22, engaging the threaded extremity of said axle. The outer surface of the box is also provided with the usual ribs 23, which are adapted to engage grooves in thohub of the wheelin. the ordinary and'wcll-known manner in order to 1001; said wheel to the axlc-box. The portion 11 of the spindle forms a seat for a '90 packing-ring 24, said ring being preferably of the shape shown in Fig. 4 and being composed of any suitable material adapted for the purpose. A similar but smaller packingring 25 surrounds the inner portion of tho outer reduced extremity olF'the spindle adjacent to theshoulder 12. Fig. 1 ot'tho drawi'ngs shows these rings in proper position on the spindle. Now when the spindle'is forced into the axle-box the shoulders Band 12' of too I the spindle and the shoulders 16 and 20 of the box tend to force and compress the annular thereof. 7 After the box and axle are thus adjusted together the nut 22 is then screwed onto the extremity of the spindle, and the several parts are thus properly adjusted together. \Vhen thus connected, it is obvious that it would be very ditticult for any dirt or sediment to pass into the box between said box andspindle, inasmuch as the packing rings 24 and 25 completely fill up the spaces.

of the registering annular grooves, and thus effectually close the joints. On the other hand it is equally difiicult for the oil or other lubricant toescape from within the journalbox. The annular shoulder-1O of the spindle, it will be observed, will contact with the shoulder 1 8 of the box, and thus limit the extent to which the axle can be forced'into' the box. 'lhese coacting shoulders are therefore advisably employed. However, if preferred, they could be omitted without departing from the spirit and scope of, my invention, and in that event the spindle \vould'con'tinue outwardly of the same diameter as the portion 11 thereof as far as the end shoulder 12, and the bore of the axle-box wonld be of course of a. corresponding diameter.

In Fig.5 of the drawings l have shown a slightlymodified form of construction, in which instead of employing the end shoulder 12 and the annular groove 13 near the outer end of the spindle I provide the exterior surface of the box 15 with an annular shoulder 26 and with an annular groove 27, adjacent to said shoulden' A modifiedform of nut for the end .of the spindle is employed in this modification. This nut is indicated by the numeral 22- and isprovided with an annular should-er 2 which fits against the end of the axle-box and is also formed at its'inner end withan extension 29 of greater diameter than the threaded portion of the nut. This extension is not threaded i'nteriorly, but is formed Within its bore withan annular shoulder'30, which is opposed to the annular shoulder 26 of the axle-box. It is also formed with an annular groove 31, which registers with the annulargroove 27. \Vithin these registering annular grooves the? packing-ring is adapted to be forced, so as'to fill up the space and tightly clb's'e'tlie joint. "I'also show in Fig. 5

. an improved ineans'of 'feeding'the oil or lubrican't to 'the parts. I't'co'n'sists of tapping a recess 32 from theouter end of the spindle.

inwa'rdl y foradesired distance and then running a branch recess 33 downwardly. The

' oil can then be readily fedthrou'gh the recess 2 and pass down the branch re'cessfib to the parts to be lubricated. After the oil is fed intofthe recess 32 the closed nut is adjusted over the end of the'spindle to prevent the oil from escaping What- I claim as lu'yinvcntion is- 1. .In a vehicle-axle andbox, the combination, of an axleprovided with a groove therearound,=one of the side walls of said groove extending out beyond the grooved surface to form a projecting shoulder, an axle-box provided with an internal groove therearound, one o: the sidetwallsof said groove extending inwardly heyondthe grooved surface to form a projecting shoulder, said shoulder, when the parts are fitted together, being opposed to the shoulder of the axle, and the two grooves of the box and axle registering, and a packing adapted tobe compressed into the registering grooves by the action of the opposed shoulders.w

2. In a vehicle-axle and box, the combination of an axlevprovided near its outer end with a shoulder therearound and with an encircling groove adjacent to the s'ideof the shoulder, and also provided at a-point farther inward with another shoulder, and with a groove adjaceut to the side of said shoulder,

an axle-box provided with sets of shoulders and'with sets of grooves,'the shoulders when the parts are fitted together being opposed to the shoulders of the axle,-and the grooves registering with the grooves of said axle, and packings adapted to be compressed into the registering grooves by the act ion of the opposed shoulders, when the parts are fitted together.

3.v In a venicle-axle and box, the combination, of an axle provided with a shoulder .therearound and with an encircling groove adjacent to the side of the shoulder, said axle also provided with another shoulder at a point vided with a shoulder and wit-ha groove ad-' .nearer the end of the axle, an axle-box'pro-fl jacent. to the side vof the shoulder, and also .providedwith another shoulder, the shoulders I of the box, when the parts are fitted together,

being opposed to the shoulders of the axle,

.and the grooves registering with the grooves-.

of said axle, and packing adapted to be compressed into registering grooves by one'set ot the opposed shoulders.

4, In a veh'icle-axle'and-box, the combination, with an axle, an axle-box, and an end nut, one of said-parts being provided with a shoulder therearound,and with a, groove adjacent to the side of the shoulder, and another of said parts with a shoulder and with a groove adjacent to the side thereof, the shoulders,when theparts are fitted together, being opposed, and the grooves registering,

of a packing adapted, when the parts are fitted together to be compressed into the registering grooves by the opposed shoulders.
